type ByteInt = Integer attribute (Size = BitSizeOf (Byte));
ByteInt is a signed integer type which is one “unit” wide. On most platforms one unit has 8 bits, therefore the type is prefixed “byte-” and usually has a range of -128 .. 127.
ByteInt in GNU Pascal is compatible to signed char in GNU C.
There are lots of other integer types in GPC, see Integer Types.
ByteInt is a GNU Pascal extension.
ByteInt in GNU Pascal corresponds to ShortInt in Borland Pascal.
